No shape
Points: 0
Pick a shape type on the left (Triangle, Square, etc.). Click points on the canvas where you want them. Most shapes need at least 3 points - just keep clicking. When you're done, press F or double-click to finish.
For circles: click and drag to draw. The center is where you start dragging, and the radius extends to where you stop. It's the quickest way to create a circle.
If you want to draw something with a weird number of sides, pick "Freeform" instead. Click however many points you need, then click the first point again to close the shape.
Draw any shape and you get all the numbers instantly - side lengths, angles, perimeter, area. For triangles you also get heights, medians, and what type it is (equilateral, isosceles, right angle, etc).
Click the Select tool and click a shape to see everything about it in the right panel.
Don't want to draw? Go to BUILDER and just enter numbers. Perfect square, perfect triangle, whatever - it builds it centered on the canvas. Works for equilateral triangles, isosceles, right triangles, squares, rectangles, pentagons, hexagons.
DISPLAY has checkboxes for medians (lines from corners to opposite midpoints), altitudes (perpendicular lines), angle bisectors (split angles), and circumcircle (circle through all corners). They're just to help you visualize - toggle them on/off to see what actually happens.
Picked a shape? Use the buttons below the canvas - Rotate (type degrees), Scale (multiply size), Mirror (flip it). Numbers update as you go.
Click Projects to save. Everything stays in your browser - nothing goes anywhere. Load it back later, rename it, delete it, whatever.
F finishes the shape. Z undoes your last point. Q clears everything.
